TECHNICAL
MANUAL
This manual should remain with the unit.
RTS Automatic Transfer Switch
A new standard of reliability
Generac Power Systems, Inc., hereafter referred to as the “manu-
facturer”, cannot anticipate every possible circumstance that
might involve a hazard. The warnings in this manual, and on tags
and decals affixed to the unit are, therefore, not all-inclusive. If
using a procedure, work method or operating technique the manu-
facturer does not specifically recommend, ensure that it is safe for
others. Also make sure the procedure, work method or operating
technique chosen does not render the transfer switch unsafe.
Throughout this publication, and on tags and decals affixed to the
generator, DANGER, WARNING, CAUTION and NOTE blocks are
used to alert personnel to special instructions about a particular
operation that may be hazardous if performed incorrectly or care-
lessly. Observe them carefully. Their definitions are as follows:
DANGER
After this heading, read instructions that, if not
strictly complied with, will result in personal injury,
including death, or property damage.
After this heading, read instructions that, if not
strictly complied with, may result in personal inju-
ry or property damage.
After this heading, read instructions that, if not
strictly complied with, could result in damage to
equipment and/or property.
NOTE:
After this heading, read explanatory statements that require
special emphasis.
These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance with the special
instructions while performing the service are essential to prevent-
ing accidents.
Four commonly used safety symbols accompany the DANGER,
WARNING and CAUTION blocks. The type of information each
indicates follows:
This symbol points out important safety informa-
tion that, if not followed, could endanger per-
sonal safety and/or property.
This symbol points out potential explosion haz-
ard.
This symbol points out potential fire hazard.

GENERAL HAZARDS
Any AC generator that is used for backup power if a NORMAL •
(UTILITY) power source failure occurs, must be isolated from
the NORMAL (UTILITY) power source by means of an approved
transfer switch. Failure to properly isolate the NORMAL and
STANDBY power sources from each other may result in injury
or death to electric utility workers, due to backfeed of electrical
energy.
Improper or unauthorized installation, operation, service or •
repair of the equipment is extremely dangerous and may result
in death, serious personal injury, or damage to equipment and/
or personal property.
Extremely high and dangerous power voltages are present inside •
an installed transfer switch. Any contact with high voltage ter-
minals, contacts or wires will result in extremely hazardous,
and possibly LETHAL, electric shock. DO NOT WORK ON THE
TRANSFER SWITCH UNTIL ALL POWER VOLTAGE SUPPLIES
TO THE SWITCH HAVE BEEN POSITIVELY TURNED OFF.
Competent, qualified personnel should install, operate and ser-•
vice this equipment. Adhere strictly to local, state and national
electrical and building codes. When using this equipment,
comply with regulations the National Electrical Code (NEC),
CSA Standard; C22.1 Canadian Electric Code and Occupational
Safety and Health Administration (OSHA) have established.
Never handle any kind of electrical device while stand-•
ing in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
Remove all jewelry (such as rings, watches, bracelets, etc.) •
before working on this equipment.
IMPORTANT SAFETY INSTRUCTIONS
* SAVE THESE INSTRUCTIONS! Read the following information carefully before attempting to
install, operate or service this equipment. Also read the instructions and information on tags,
decals, and labels that may be affixed to the transfer switch. Replace any decal or label that is no
longer legible.
DANGER! Connection of a generator to an electrical system normally supplied by an electric util-
ity shall be by means of suitable transfer equipment so as to isolate the electric system from utility
distribution system when the generator is operating (Article 701 Legally Required Standby Systems

1.1 INTRODUCTION
This manual has been prepared especially for the purpose of famil-
iarizing personnel with the design, application, installation, opera-
tion and servicing of the applicable equipment. Read the manual
carefully and comply with all instructions. This will help to prevent
accidents or damage to equipment that might otherwise be caused
by carelessness, incorrect application, or improper procedures.
Every effort has been expended to make sure that the contents
of this manual are both accurate and current. The manufacturer,
however, reserves the right to change, alter or otherwise improve
the product at any time without prior notice.
1.2 EQUIPMENT DESCRIPTION
The automatic transfer switch is used for transferring electrical
load from a UTILITY (NORMAL) power source to a EMERGENCY
( STANDBY) power source. Such a transfer of electrical loads
occurs automatically when the UTILITY power source has failed or
is substantially reduced and the EMERGENCY source voltage and
frequency have reached an acceptable level. The transfer switch
prevents electrical feedback between two different power sources
(such as the UTILITY and EMERGENCY sources) and, for that rea-
son, codes require it in all standby electric system installations.
The transfer switch consists of a transfer mechanism, a relay con-
trol, and a terminal strip for connection of sensing wires.
This switch is suitable for control of motors, electric discharge
lamps, tungsten filament and electric heating equipment and the
tungsten load does not exceed 30% of the switch rating.
The transfer switch is for use in optional standby systems only.
A 100A rated switch is suitable for use on circuits capable of
delivering not more than 10,000 RMS symetrical amperes, 250
VAC maximum, when protecty by a 100A maximum circuit breaker
(Siemens types QP or BQ) or 150A maximum circuit breaker
(Square D Q2, Westinghouse CA-CAH, General Electric TQ2 and
Siemens QJ2).
A 200A rated switch is suitable for use on a circuit capable of
10,000 rms symmetrical amperes, 240 VAC when protected by
a circuit breaker without an adjustable short time response or by
fuses.
1.3 TRANSFER SWITCH DATA
DECAL
A DATA DECAL is permanently affixed to the transfer switch enclo-
sure. Use this transfer switch only within the specific limits shown
on the DATA DECAL and on other decals and labels that may be
affixed to the switch. This will prevent damage to equipment and
property.
When requesting information or ordering parts for this equipment,
make sure to include all information from the DATA DECAL.

2.1 INTRODUCTION TO
INSTALLATION
This equipment has been wired and tested at the factory. Installing
the switch includes the following procedures:
Mounting the enclosure.•
Connecting power source and load leads.•
Connecting the generator start and sensing circuit.•
Connecting any auxiliary contact (if needed)•
Testing functions.•
2.2 UNPACKING
Carefully unpack the transfer switch. Inspect closely for any dam-
age that might have occurred during shipment. The purchaser must
file with the carrier any claims for loss or damage incurred while in
transit.
Check that all packing material is completely removed from the
switch prior to installation.
2.3 MOUNTING
Mounting dimensions for the transfer switch enclosure are in
this manual. Enclosures are typically wall-mounted. See the
“Installation Diagram” section.
Handle transfer switches carefully when install-
ing. Do not drop the switch. Protect the switch
against impact at all times, and against con-
struction grit and metal chips. Never install a
transfer switch that has been damaged.
Install the transfer switch as close as possible to the electrical
loads that are to be connected to it. Mount the switch vertically to
a rigid supporting structure. To prevent switch distortion, level all
mounting points. If necessary, use washers behind mounting holes
to level the unit.
2.4 CONNECTING POWER SOURCE
AND LOAD LINES
DANGER
Make sure to turn OFF both the UTILITY
(NORMAL) and EMERGENCY (STANDBY) power
supplies before trying to connect power source
and load lines to the transfer switch. Supply
voltages are extremely high and dangerous.
Contact with such high voltage power supply
lines will result in an extremely hazardous, pos-
sibly lethal, electrical shock.
Wiring diagrams and electrical schematics are provided in this
manual. Power source and load connections are made at a transfer
mechanism, inside the switch enclosure.
2.4.1 2-POLE MECHANISM
These switches (Figure 2.1) are used with a single-phase system,
when the single-phase NEUTRAL line is to be connected to a
Neutral Lug and is not to be switched.

Conductor sizes must be adequate to handle the maximum current
to which they will be subjected to, based on the 75°C column of
tables, charts, etc. used to size conductors. The installation must
comply fully with all applicable codes, standards and regulations.
Before connecting wiring cables to terminals, remove any surface
oxides from the cable ends with a wire brush. All power cables
should enter the switch next to transfer mechanism terminals.
If ALUMINUM conductors are used, apply corrosion inhibitor to
conductors. Tighten terminal lugs to the torque values as noted on
the decal located on the inside of the door. After tightening terminal
lugs, carefully wipe away any excess corrosion inhibitor.
All power cables should enter the switch next to the transfer
mechanism terminals.
Use a torque wrench to tighten the conductors,
being sure not to over tighten, or damage to
the switch base could occur. If not tightened
enough, a loose connection would result, caus-
ing excess heat which could damage the switch
base.

Disconnect transfer switch from all power
sources by approved means, such as a main
circuit breaker(s).
A manual HANDLE is shipped with the transfer switch. Manual
operation must be checked BEFORE the transfer switch is operated
electrically. To check manual operation, proceed as follows:
1. Turn the generator’s AUTO/OFF/MANUAL switch to OFF.
2. Turn OFF both UTILITY and EMERGENCY power supplies to
the transfer switch, with whatever means provided (such as
the main line circuit breakers).
3. Note position of transfer mechanism main contacts by
observing the moveable contact carrier arm.
• Manual operation handle towards the top of switch mecha-
nism - LOAD terminals (T1, T2) are connected to UTILITY
terminals (N1, N2).
• Manual operation handle towards the bottom of switch
mechanism - LOAD terminals (T1, T2) are connected to
EMERGENCY terminals (E1, E2).
Do not use excessive force when operating the
transfer switch manually or damage could be
done to the manual handle.
3.2.1 CLOSE TO NORMAL SOURCE SIDE
Before proceeding, verify the position of the switch by observing
the position of manual operation handle in Figure 3.1. If the handle
is UP, the contacts are closed in the NORMAL position, no further
action is required. If the handle is DOWN, proceed with Step 1.
Step 1: With the handle inserted into the actuating shaft, move
handle UP. Be sure to hold on to the handle as it will move
quickly after the center of travel.
3.2.2 CLOSE TO EMERGENCY SOURCE SIDE
Before proceeding, verify the position of the switch by observing
the position of the manual operation handle in Figure 3.1. If the

9. Set the AUTO/OFF/MANUAL switch to the OFF position to shut
down the generator.
NOTE:
Do NOT proceed until generator AC output voltage and frequen-
cy are correct and within stated limits. If the no-load voltage is
correct but no-load frequency is incorrect, the engine governed
speed probably requires adjustment. If no-load frequency is
correct but voltage is not, the voltage regulator may require
adjustment.
3.4 GENERATOR TESTS UNDER
LOAD
1. Set the generator's main circuit breaker to its OFF or OPEN
position.
2. Manually actuate the transfer switch main contacts to their
EMERGENCY (STANDBY) position. Refer to the "Manual
Operation" section.
3. To start the generator, set the AUTO/OFF/MANUAL switch to
MANUAL. When engine starts, let it stabilize for a few min-
utes.
4. Turn the generator's main circuit breaker to its ON or CLOSED
position. The generator now powers all LOAD circuits. Check
generator operation under load as follows:
• Turn ON electrical loads to the full rated wattage/amper-
age capacity of the generator. DO NOT OVERLOAD.
• With maximum rated load applied, check voltage and
frequency across transfer switch terminals E1 and E2.
Voltage should be greater than 230 volts and frequency
should be greater than 59 Hertz.
• Let the generator run under rated load for at least 30 min-
utes. With unit running, listen for unusual noises, vibra-
tion, overheating, etc., that might indicate a problem.
5. When checkout under load is complete, set main circuit
breaker of the generator to its OFF or OPEN position.
6. Let the generator run at no-load for several minutes. Then,
shut down by setting the AUTO/OFF/MANUAL switch to its
OFF position.
7. Move the switch's main contacts back to their UTILITY posi-
tion. For example, load connected to UTILITY power supply.
Refer to the "Manual Operation" section. Handle and operating
lever of transfer switch should be in UP position.
8. Turn on the UTILITY power supply to transfer switch, using
whatever means provided (such as a UTILITY main line circuit
breaker). The UTILITY power source now powers the loads.
9. Set the generator's AUTO/OFF/MANUAL switch to its AUTO
position. The system is now set for fully automatic operation.
